During those two years, he engineered trades that sent key players to the New York Yankees, such as Bob Cerv and Ralph Terry, but his most notable deal came on December 11, 1959, in which Carroll sent 25-year-old outfielder Roger Maris to the Yankees along with two other players for Don Larsen (author of a World Series perfect game three years earlier), Marv Throneberry, Hank Bauer and Norm Siebern.
With the aid of the short right-field porch in Yankee Stadium, Maris set a single-season record with 61 home runs in 1961, just two years after leaving the A's.
Carroll's dealings with the Yankees were controversial because the Athletics, under owner Arnold Johnson, sent many top players to New York in apparently one-sided trades during the mid-to-late-1950s.
Johnson previously had not handed the general manager title to a specific executive, preferring to divide the GM responsibilities among himself, Selkirk and Carroll.
Johnson died suddenly from a cerebral hemorrhage in 1960 while he was in Florida attending the Athletics' spring training preparations for the upcoming season.
